Cloud Infrastructure Management Platform
Software Design Specification (SDS)
Version: 1.0 (V1 – Enterprise Foundation)
1. Architectural Overview
The platform adopts a Control Plane and Data Plane architecture.
- Control Plane manages APIs, identity, orchestration, policy, and state.
- Data Plane executes infrastructure operations via agents and providers.
2. High-Level Components
2.1 Management Layer
- Tenant Management Console
- Provider / Operations Console
In Version 1, both consoles MAY be implemented as a single UI with strict role-based access control.
2.2 API Gateway
Responsibilities:
- Authentication and authorization
- API namespace separation
- Request validation and rate limiting
- Centralized audit logging hook
2.3 Core Services
| Service | Responsibility |
|---|---|
| Identity Service | Users, roles, RBAC |
| Resource Manager | Projects, quotas, metadata |
| Compute Service | Virtual machine lifecycle |
| Network Service | Virtual network management |
| Storage Service | Volume or object storage |
| Job Service | Workflow orchestration and retries |
| Audit Service | Append-only audit logging |
| Metering Service | Usage aggregation |

4. API Design Principles
- REST-based APIs
- Versioned endpoints
- Clear separation between tenant and provider APIs
Namespace Examples
- /api/tenant/v1/*
- /api/ops/v1/*
- /api/common/v1/*
5. Job & Workflow Design
Job Lifecycle States
- PENDING
- RUNNING
- SUCCEEDED
- FAILED
- RETRYING
Design Characteristics
- Idempotent create operations
- Retry for transient failures only
- Persistent job state storage
6. Provider & Agent Architecture
Provider Interfaces
- Compute Provider
- Network Provider
- Storage Provider
Agent Responsibilities
- Execute infrastructure-level operations
- Report actual state to the control plane
- Emit audit and telemetry data
7. Reconciliation Mechanism
- Periodic reconciliation loop
- Desired state vs actual state comparison
- Drift handling via:
- Automated correction
- Operator alert and incident escalation
8. Security Architecture
- Token-based authentication
- RBAC enforcement across services
- Encrypted secret storage
- Distributed request tracing
9. Deployment Model (V1)
- Stateless API services
- PostgreSQL as primary datastore
- Message queue for job distribution
- Agent deployment per infrastructure cluster
10. Future Evolution
- Multi-cluster federation
- Kubernetes services
- Policy-as-Code
- Billing and invoicing
- Application marketplace
